Acquired surface alexia in Spanish: a case report

This paper reports a case study of acquired surface alexia in Spanish and discusses the most suitable tests to detect this syndrome in a writing system that is very regular for reading at the segmental and supra-segmental levels. Patient MM has surface alexia characterized by quantitatively good performance in reading words and pseudowords; accurate but slow and syllabic reading of words, nonwords and sentences; good performance in lexical decision tasks including words and nonwords; errors in lexical decision with pseudohomophones; and homophone confusions. This pattern of reading can be interpreted as a disorder in the lexical reading route and overdependence on the non-lexical route. We discuss nonlexical impairments and the interpretation of alexia and suggest tasks to identify surface alexia in a shallow orthography.     

Activation of adenosine receptors in the posterior cingulate cortex impairs memory retrieval in the rat

Adenosine A1 and A2A receptor agonists and antagonists have been reported to alter learning and memory. The aim of our study was to investigate the involvement of adenosinergic system in memory retrieval into posterior cingulate cortex (PCC) of Wistar rats. To clarify this question, we tested specifics agonist and antagonists of adenosine A1 and A2A receptors in rats submitted to a one-trial inhibitory avoidance task. The stimulation of adenosine A1 and A2A receptors by CPA and CGS21680, respectively, impaired memory retrieval for inhibitory avoidance task, into PCC. These findings provide behavioral evidence for the role of adenosinergic system in the memory retrieval into PCC.     

The role of parametric assumptions in adaptive Bayesian estimation

Variants of adaptive Bayesian procedures for estimating the 5% point on a psychometric function were studied by simulation. Bias and standard error were the criteria to evaluate performance. The results indicated a superiority of (a) uniform priors, (b) model likelihood functions that are odd symmetric about threshold and that have parameter values larger than their counterparts in the psychometric function, (c) stimulus placement at the prior mean, and (d) estimates defined as the posterior mean. Unbiasedness arises in only 10 trials, and 20 trials ensure constant standard errors. The standard error of the estimates equals 0.617 times the inverse of the square root of the number of trials. Other variants yielded bias and larger standard errors.     

Hyperbolic modeling and assessment of hypothetical health behaviors during a viral outbreak using crowdsourced samples

The COVID-19 pandemic provided an opportunity to investigate factors related to public response to public health measures, which could help better prepare implementation of similar measures for inevitable future pandemics. To understand individual and environmental factors that influence likelihood in engaging in personal and public health measures, three crowdsourced convenience samples from Amazon Mechanical Turk (MTurk) completed likelihood-discounting tasks of engaging in health behaviors given a variety of hypothetical viral outbreak scenarios. Experiment 1 assessed likelihood of mask wearing for a novel virus. Experiment 2 assessed vaccination likelihood based on efficacy and cost. Experiment 3 assessed likelihood of seeking health care based on number of symptoms and cost of treatment. Volume-based measures and three-dimensional modeling were used to analyze hypothetical decision making. Hypothetical public and personal health participation increased as viral fatality increased and generally followed a hyperbolic function. Public health participation was moderated by political orientation and trust in science, whereas treatment-seeking was only moderated by income. Analytic methods used in this cross-sectional study predicted population-level outcomes that occurred later in the pandemic and can be extended to various health behaviors.     

Contextual framing of loss impacts harm avoidance during risky spatial decisions

Although the same decision to act can occur in multiple contexts, how these contexts differentially influence behavior is not well understood. In this paper, we investigate whether contextual framing affects individuals' behavior in spatial decision making. Although previous research suggests that individuals' judgments are sensitive to contextual (and particularly moral) factors of a scenario, no work has addressed whether this effect extends to spatial decisions. To investigate the impact of context on perceptual sensorimotor behavior, we superimposed two moral dilemmas (which we call help and harm) on a spatial decision-making paradigm. The basic task required participants select a target area while avoiding an overlapping nontarget area. Although the visuospatial task was constant, the moral context was changed when participants had to execute either a drone missile strike on enemies in the harm context or deliver ammunition to allies in the help context. Participants more strongly avoided losses in the harm context, reflected by a greater selection bias away from the nontarget (i.e., allies) on drone strike trials. These findings suggest that the contextual framing of a subjective perceived loss on a spatial decision can drive avoidant motor execution behavior.     

The study of behavioral ethics within organizations: A special issue introduction

Ethics has emerged as one of the most critical issues facing organizations. Given its importance, an extensive literature has evolved to understand the causes and consequences of (un)ethical decision making and behaviors in organizations. To date, much of this research has relied on research methods (e.g., experiments) that emphasize internal validity and control over external validity and generalizability. Although very informative, such studies frequently utilize samples that are not representative of working adults and their designs often fail to capture the contextual complexity that defines the day-to-day realities of organizational life. In this light, this special issue of Personnel Psychology encouraged scholars to investigate ethics within organizations and to offer rich theoretical explanations for why ethical failures and successes occur. The articles in this special issue address this important research agenda and make significant contributions to our understanding of ethics in organizations. Our introduction synthesizes these works, provides an overview of issues facing the broader behavioral ethics literature, and discusses areas for future research.

Socialized charismatic leadership, values congruence, and deviance in work groups

The authors conducted a field study to investigate the relationship between socialized charismatic leadership and deviance in work groups. Because socialized charismatic leaders are thought to play an ethical leadership role, the authors hypothesized that the socialized charismatic leadership style would be associated with reduced deviance in the leader's work group. This prediction was supported for both the interpersonal and the organizational dimensions of deviance. Next, the authors examined the mediating role of values congruence. The results were partially supportive of the values congruence mediating hypothesis. Implications for future research and for management are discussed.     

Mechanisms of predictive and diagnostic causal induction

In predictive causal inference, people reason from causes to effects, whereas in diagnostic inference, they reason from effects to causes. Independently of the causal structure of the events, the temporal structure of the information provided to a reasoner may vary (e.g., multiple events followed by a single event vs. a single event followed by multiple events). The authors report 5 experiments in which causal structure and temporal information were varied independently. Inferences were influenced by temporal structure but not by causal structure. The results are relevant to the evaluation of 2 current accounts of causal induction, the Rescorla-Wagner (R. A. Rescorla & A. R. Wagner, 1972) and causal model theories (M. R. Waldmann & K. J. Holyoak, 1992).
